Jim
Minerich, a 4th Grade teacher in Pequot Lakes, MN, uses a hand-held GPS
(Global Positioning System) to track migrating animals with Journey North. Minerich's students use a hand-held GPS (Global Positioning
System) to assist them in determining the distance and direction that
satellite tagged animals
travel between data updates.

"Our
classroom uses a hand-help GPS to help us determine the distance
and direction that each of the satellite-collared caribou move from update
to update. Our GPS has as one of its functions a distance between
waypoints
function. Even though we know the data is days apart, the direction
is given to us in degrees. Our GPS does not use decimals so we have
learned how to convert decimals to min/sec by multiplying."
